Blog by Joyal Taylor

This is the third article by Joyal (known online as holymolar). Again it is with pleasure that I put this on the blog. Joyal had emailed me that he was working on this piece for the blog. I was looking forward to reading his thoughts on this. Others have mentioned the problem to me when they used the black super glue. Joyal has done some good experimenting and I am pretty certain he has gotten to the root of the problem. Thanks Joyal for taking time to write-up your experience and tips on this patching process. This is a what rebornpipes is all about – taking ideas and experimenting and improving them. Without further introduction have a read on what Joyal has learned.

The first few times that I patched stem holes and deep tooth marks with black superglue, I ended up with white margins like these: (very evident when a flashlight is shined on the patch at an angle).

At first, I thought that I must have contaminated it by sanding before the glue had totally set. But now, I’m convinced it was because I didn’t remove all of the oxidation beforehand. I’ve learned a few tricks with black superglue patching.

Here’s the before photos of a Dr Grabow stem that I recently patched. It’s not a high quality vulcanite but a relatively soft rubber.

Tip #1 – Absolutely ALL oxidation and oils must be removed before patching. There are many ways to remove oxidation but, for this, I prefer the most aggressive method that I know – A bleach bath for an hour or more. Then a 1 hour alcohol bath to remove the bleach smell and taste. The bleach causes surface pitting but, in my mind, that means it has removed the deepest oxidation. (Sometimes I’ll follow with a Oxyclean bath as well). After the bleach and alcohol, lots and lots of sanding is necessary to smooth down the pitting. I use 220-800 grit with water.

Tip #2 – Clean out the hole with a small round burr in a Dremel. Remove all oxidation and discolorations from inside the hole. “Feather” the edge which makes for better blending of the glue/stem junction and it also removes any microscopic particles of oxidation that may be hiding in the ragged edges.

Tip #3 – Now use 1000 grit sandpaper on the edges to smooth it out some more. Remove any dust or oils with an alcohol wipe.

I sand down the overfill (220-2500 grit) until it’s even with the surface. (If necessary, I’ll freshen up the bit with needle files). Then micro mesh (4000 -12000), carnauba, and buff.

Here’s the after photos on that Dr Grabow stem before final polishing/waxing – .so it can be seen better without the glare of the camera flash on fully polished stems. No more “ring around the collar”.

Sometimes, on good quality vulcanite, I have difficulty seeing where the patches were.
